COMBINED MEASURING AND SAMPLiNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 725,915, dated April21, 1903.

Application filed January 19,1903. Serial No. 139,571. No model.)

To all 10710122, it may concern.-

Be it known that I, HARRY S. BADGER,a citizen of the United States ofAmerica, residing at Truro, in the county of Oolchester, in the Provinceof Nova Scotia and Dominion of Canada, have invented a new and usefulCombined Measuring and Sampling Machine, of which the following is aspecification.

My invention relates to measuring or weighing machines whichautomatically dump their contents from each end alternately, eachalternate movement being recorded on a selfregistering device attachedto the stand of the machine; and the object of my invention is tocombine a sampling device with such a machine in order to obtain asample at each movement of the machine of the material passing throughit. I attain this object by the mechanism illustrated in theaccompanying drawings, in which- Figure l is a side elevation of themachine, showing the sampling-spout, one of the tankcompartments emptyand the other one filled ready to dump, also a portion of the launder.Fig. 2 is a plan of the tank and its attachments without the frame orother accessories. Fig. 3 is an end elevation of the machine with thetank partially broken away, showing the method of connecting it with theframe and also showing a portion of the launder. Fig. 4 is a plan of theframe separate from the other parts of the machine. Fig. 5 is a plan ofthe movable guide. Fig. 6 is an end elevation of the same. Fig. 7 is aside elevation of the bearing-stand. Fig. 8 is a section of the same online 0 cl. Fig. 9 is the journal. Fig. 10 is a section of the same online a b. Fig. 11 is a plan of the steel support on which the journalrests. Fig. 12 is an end view of the same. Fig. 13 is an edge view ofthe striker. Fig. 14 is a side view of the same.

Similar letters refer to similar parts th ro u ghout the several views.7

In the drawings, A is the frame of the machine, which is of cast metal.

B is the tank, which is made of sheet metal and is divided into twocompartments of equal capacity by the division-plate a.

c is the sampling-spout, which of sheet metal and is attached to thetank and moves with it. It is open on the top, where it projects overthe tank and catches a sample of the material being discharged into thetank at each movement of said tank and conveys it to a bucket or anyreceptacle placed to receive it.

d is the recording instument, which is attached to the top of the frameand is operated by the striker e, which is attached to one side of thetank, coming in contact with the leverf at each movement of the tank.

9 is the launder, which conveys the material to thetank.

h h are the bearing-stands, which are riveted to the tank and whichreceive the journal and guides.

k is the recess for the guides.

Z is the bore to receive the journal.

m is the stationary guide, which is an in tegral part of the frame. 1

n is the movable guide, which is adjustably attached to the frame.

0 is the journal, which has two pivot-lines a w, on which the tank, withits attachments, is pivoted.

The indentions s in Figs. 11 and 12 are for the reception of thepivot-lines 00 a of the journal.

1; a; are recesses for the reception of the supports shown in Figs. 11and 12.

The guides m and n are set concentric to the pivot-lines m 00 0f thejournal 0 and are for the purpose of preventing the pivots from becomingdisplaced.

pp are stops on which the empty compartment of the tank rests while theopposite one is being filled.

The operation of the machine is as follows: The material (a goldsolution, for. instance) is delivered into one compartment'of' the tankby the launder g, and when the solution reaches the water-level line 10y its-weight will overbalance the empty compartment and the contentswill be emptied andthe opposite compartment will be brought into theproper position to receive the solution, and so on,

each compartment being filled and emptied alternately, and thesampling-spout being attached to the tank will secure a sample of thesolution at each movement as it passes through the falling liquid anddeposit it into any convenient receptacle placed under the spout toreceive it; also, the striker e at each movement of the tank will comeinto contact with the lever fot the recording instrument, thusautomatically registering each or each alternate movement, and thecontents of the tank having been previously ascertained the recordinginstrument will show the results at any time.

Having described and illustrated my invention, what I claim, and desireto secure by Letters Patent, is-- 1. A tilting tank divided into twocompartments and adapted to the measurement of liquids or othermaterial, a registering device, and a frame supporting said tank andregistering device, in combination with a sampli n gspout attached tosaid tank and adapted to take a sample of the material passing into saidtank at each movement of the same; substantially as described.

2. In a measuring and sampling machine the combination of a tilting tankadapted t0 lines, with a sampling-spout attached to said u tank andmovable therewith; substantially as described, and for the purposespecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HARRY S. BADGER.
